SELF-HEATING SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 613,396, dated November 1, 1898.

Application filed December 30, 1897. Serial No. 664,679. (No model.)

T0 at whom it may concern:

Be it known that I, WILLIAM PULLEN, mechanical engineer, of 11 Ashton Row, Birmingham, in the county of Warwick, England, late of 17 Lime Grove, Moseley road, Birmingham, aforesaid, have invented certain new and useful Improvements in Lamps or Burners for Heating Soldering-Irons, &c., (for which I have obtained Letters Patent in Great Britain, No. 3,456, dated February 18, 1895,) of which the followingis a specification.

I will describe a construction embodying my invention and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is an elevation of a soldering-iron. Fig. 2 is a sectional elevation thereof. Fig. 3 is a crosssection on line X X of Fig. 2. Fig. 4 is a crosssection on line Y Y of Fig. 2. Fig. 5 is a sectional view of a modified form.

A represents a vessel or receptacle forming a handle of a soldering-iron and which contains naphtha or other like liquid. It is preferably closed at one end bya fixed cap 0 and at its other end with a removable cap D.

B represents a tube one end of which projects through the cap C and is held therein, while its other end is adjustably connected with a casing G. The tube and vessel contain a wick E, which is supported in the tube by a twisted wire F and which feeds the naphtha to a burner H. The burner H is carried by the casing G and is in communication with a recess g, forming a reservoir. This recess is in communication by a passage g with the end of tube B, which end is closed bya plug N. The plug is preferably provided with perforations n n and with a valve 9 which controls the passage 9 K represents a tube surrounding the burner. It is provided with a contracted end is to confine the flame from the burner, and with openings or perforations k to admit air to the burner. A tube I surrounds the tube K. This tube is provided with openings or perforations 11, which register with the openings or perforations'k It is also provided with ribs or ridges '6 on which a sleeve J works to control the opening in the tube I.

L represents a copper bit removably fixed on the tube I by means of a small screw Z. The bit L may be provided with openings Z as shown in Figs. 1 and 2, for the heated air and flame to pass through, or, as shown in Fig. 5, the bit may be without the openings 1*, and in this case the openings would have to be provided in the upper part of the tube I.

By first removing the cap D from the vessel A the latter can, when inverted, be filled with naphtha or other suitable liquid fuel, which is absorbed by the wick E. Before heating the copper bit L a little naphtha is poured into the cup 0'' on the cap 0 and ignited for the purposes of warming the upper part of the tube B in the casing G. When these have become warm, the passage 9 is slowly opened by turning the tube B to withdraw the valve 9 therefrom, thus permitting the vapor of the naphtha passing through the openings 01 n and the passage g to the burner H.

When it is desired to convert the solderingiron into a plumbers tool for heatinglead, or

for making plumbers joints, or for heating and fusing metals, or for various other purposes to which a blowpipe is generally applied, or as a painters burning-off torch, it is only necessary to remove the copper bit L, when a flame of high temperature will issue from the end of tube I.

Instead of the inner tube K being-fixed to the upper part of the casing G, as shown in Fig. 2, this part, with the contracted outlet, may be fixed to the tube I, as shown in Fig. 5, at some little distance above the air-inlets in the tubes, thus simplifying the arrangement.

Instead of employing the valve 9 as shown in Figs. 1 and 2, for regulating the flame I may employ any other kind of valve-such, for instance, as an ordinary pin-valve O, as shown in Fig. 5, which controls the passage from the tube B to the recess g.

Instead of using the twisted wire F in the Wick E, as shown in Fig. 2, I may substitute.

a small tube P for the wire F, as shown in Fig. 5, said tube being split or otherwise formed with prongs p p at one end to engage with the wick and hold it in the tube B.

The accompanying drawings illustrate what I consider the best method of carrying out my invention; but it is to be understood that my invention is not limited to the precise details shown.

I claim as my invention 1. The combination with a suitable vessel or receptacle, a tube having one of its ends projecting into and held by said vessel, a casing carrying a burner adjustably attached to the other end of said tube, said casing being provided with a recess forming a communication between the burner and said tube, a plug intermediate the tube and casing for closing that end of the tube, anda valve provided in said plug for controlling the recess in the casing, substantially as shown and described.

2. The combination with a suitable vessel or receptacle, a tube having one of its ends projecting into and held by said vessel, a casing carrying a burner adjustably secured to the other end of said tube and forming a communication between the burner and said tube, a tube surrounding said burner, said tube being formed with a contracted end and with openings or perforations, a second tube surrounding the first-mentioned tube and provided with openings or perforations which WVILLIAH PULLEN.
